Abstract
The equilibrium distribution coefficients, k^x_o, between solid and liquid phases in Ni-base multi-component alloys have been determined by means of the experiment and also the thermodynamic calculation. The experimental results show that k^x_o's of Ni, Cr, Fe, and Co are almost unchanged for the compositions of alloys, but that k^x_o's of Nb and Ta decrease with increasing Fe and Co contents in both Ni-Cr-Fe-Mo and Ni-Cr-Co-Mo base multi-component alloys. The composition dependence of k^x_o was also obtained by the thermodynamic calculation in which the solute-interations were taken into account.
